UCCU Ransomware – In Depth Analysis

As soon as its payload is dropped on the infected computer, it may be located in one of the following Windows folders:

  • %AppData%
  • %Documents%
  • %User’s Profile%
  • %Roaming%
  • %Local%

The executable of the malware may have the following rather vulgar name:

fuckgod_jesu_crypt.exe

In addition to that, UCCU Ransomware may create a registry entry in the RUN and RUNONCE keys for the “f*ckgod_jesu_crypt” executable file to start along with Windows and begin encrypting files. The Run and RunOnce keys in which this value string may be located are the following:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

In addition to that, UCCU may delete the Shadow Copies of the infected computer, by executing the vssadmin command with one of its many parameters, for example:

vssadmin delete shadows /for={Volume of the drive, for example C:} /all

The encryption process has a wide scope of files which are targeted. The most used file extensions are encrypted, but the ransomware evades the file extensions which contain important files that can break Windows. The file types targeted are the following:

.png .3dm .3g2 .3gp .aaf .accdb .aep .aepx .aet .ai .aif .arw .as .as3 .asf .asp .asx .avi .bay .bmp .cdr .cer .class .cpp .CR2 .crt .CRW .cs .csv .db .dbf .dcr .der .dng .doc .docx .docb .docm .dot .dotm .dotx .dwg .dxf .dxg .efx .eps .erf .fla .flv .idml .iff .indb .indd .indl .indt .inx .jar .java .jpeg .jpg .kdc .m3u .m3u8 .m4u .max .mdb .mdf .mef .mid .mov .mp4 .mpa .mp3 .mpeg .mpg .mrw .msg .NEF .nrw .odb ODC-.odm .odp .ods .odt .orf .p12 .P7B .p7c .pdb .pdf .pef .pem .pfx .php .plb .pmd .pot .potm .potx .ppam .ppj .pps .ppsm .ppsx .ppt .pptm .pptx .prel .prproj .ps .psd .pst .ptx .r3d .ra .raf .rar .raw .rb .rtf .rw2 .rwl .sdf .sldm .sldx .sql .sr2 .srf .srw .svg .swf .tif .vcf .vob .wav .wb2 .wma .wmv .wpd .x3f .xla WPS-.xlam .xlk .xll .xlm .xls .xlsb .xlsm .xlsx .xlt .xltm .xltx .xlw .xml .xqx .zip Source: Malwr.com
